OIL-BURNER.

Specification of Letters Patent.

Patented July 17', 1906.

Applicatior filed August 19, 1905. Serial l lo 274.859.

To all wit/17w it may concern:

Be it known that 1, JAMES L. SMITH, a citizen of the United States, residing at Taunton, in the county of Bristol, State of Massachusetts, have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to burners, and more particularly to gas-burners, and has for its object to provide a burner of the retort-vaporizer type which will be arranged to generate gas from a volatile liquid and which will also be provided with a water-chamber disposed to receive heat from the burning gas to generate steam which will be fed to the gas, thus reducing the fuel consumption and promoting combustion.

Another object is to provide a burner of this kind including a novel arrangement of parts which will tend to produce an eflicient burner.

Other objects and advantages will be apparent from the following specification,which describes an embodiment of the present invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in both views, Figure 1 is a central vertical section of the burner. Fig. 2 is a horizontal section through the base portion on line 2 2 of Fig. 1.

Referring now to the drawings, the present invention comprises a hollow base portion 5, which is open at its top and which is circular in top plan, this base portion thus having a bottom 6 and a circular inclosing wall 7. A plurality of tubes 8 are engaged at their lower ends in openings 9, formed in the bottom 6, and lie in spaced relation to each other, these pipes being open at their upper ends and terminating short of the upper edge of the wall 7. These tubes thus form draft-passages. An oil-supply pipe 10 is passed centrally through the bottom 6 and extends upwardly into the base portion 5, and at the opposite sides of this central feed-pipe there are a pair of vertical sleeves 11, which extend somewhat above the tubes 8 and which are somewhat larger than these tubes, the lower end of the sleeves being engaged in openings 12, formed in the bottom 6 of the base portion. An overflowpipe 13 is engaged and communicates with l the interior of the base portion at a point just below the upper'ends of the tubes 8.

Disposed within the base portion around the tubes 8 there is a quantity of sand or other absorbent material which is not materially affected by heat, and it will be apparent that oil admitted through the pipe 10 will be absorbed by this material, which is indicated at 14, any excess oil being carried oil by the. pipe 13.

A cylindrical casing 15, having an open upper end and being of somewhat lesser diameter than the base portion 5, is disposed upon the upper ends of the sleeves 11 and has openings 16 in its bottom, which communicate with the interiors of these sleeves. A second and smaller cylindrical casing 17 is disposed within the casing 26, withits inclosing wall in spaced relation to that of the latter, and the upper edge of the wall of the casing 1.7 termicasings having upwardly-extending fingers and 17, respectively, at their upperedges.

A hollow cylindrical casting 18, which is open at its upper end, is disposed within the casing 17 and rests upon the bottom thereof.

.This casting has openings 19 in its bottom, which register with openings 20 in the bottom of the casing 17 and also with the openings 16, and engaged in these openings and in the sleeves 11 there are water ingress and egress pipes 22 and 21, respectively, the upper ends of these pipes being screwed into the openings 19 and the pipe-21 extending some distance up into the casting 18 to maintain a predetermined water-level. These pipes are engaged in the openings 16 and 20 in such a way as to prevent the leakage of steam through the openings around the pipe.

A cylindrical casing 23, having an open lower end, is engaged over the casting 18, with its top 24 resting upon fingers 25, which extend upwardly from the upper edge of the casting, and this casing 23 has fingers 23 at its lower edge, which rest upon the bottomof the casing 17 these two casings lying in spaced relation and the casing 23 lying also in spaced relation to the casting 18. v

A casing 26, similar in every way to the casing 23, but of a larger size, is disposed over the casing 17, resting upon the fingers 17 and having fingers 26, which rest upon the bottom of the casing 15. It will be understood that the several casings lie in spaced relation to each other at all point-s, except where the finnates short of that of the casing 1.5, these two ICO gers of one casing engage portions of another. Afil'th casing 27 which is open at its bottom, is disposed over the casing 15 and rests upon the fingers 15, and by reason of the fact that this casing also lies in spaced relation to the casing 15 a tortuous passage is formed between the several casings, communicating at one end with the interior of the body portion 5 and at its other end with the interior of the casting 18.

A chimney 29, which is cylindrical in form, has its lower edge engaged in a groove 30, formed in the upper edge 01'' the wall 7, and engaged with the upper portion of this chimney there is a depending base-flange 31 of a cap 32, having an upper portion 33 in the form of a truncated cone, the resultant oriiice 34 lying above the several casings and concentric therewith.

In operation oil is admitted to the absorbent 14: in the manner described above, and this absorbent being initially heated in any suitable manner the liquid is volatilized, and the gas passes upwardly around the outer casing 27 and out through the opening 34, above which it is ignited. ater is admitted to the casting 18 through the pipe 2] and, this casting being heated also, the water is raised to the boiling-point, and. the steam. thus generated passes through the tortuous passage 30, where it is superheated and from which it passes at a high temperature. The steam is thus fed to the gas at the point at which it leaves the sand. and passing upwardly with the gas through the chimney 29 mixes thoroughly with it to promote combustion, as mentioned in the foregoing. 'It will be understood that after the burner is in operation. its own heat will continue the volatilization of the oil and boiling of the water.

What is claimed is V 1. A burner comprising a hollow base portion, an absorbent in the base portion, a fuelsupply pipe communicating with the interior of the base portion, sleeves disposed within the base portion and engaged in. the bottom thereof, a casing disposed upon the sleeves and having openings registering therewith, said casing being open. at its top, an open water-receptacle disposed within the casing, water-pipes communicating with the receptacle and extending downwardly through the sleeves, a casing disposed over the firstnamed casing and lying in spaced relation thereto, a casing disposed over the receptacle and. lying in spaced relation. to the receptacle and to the first-named casing, and an inclosure for the casings communicating at its lower end with the interior of the base portion, said inclosure having an opening at its top.

2. A burner comprising a fuel-pan, sleeves engaged in the pan, a core disposed upon the sleeves and having a water-receptacle therewithin and a passage communicating with the water-receptacle and with the interior of the pan, and water-supply pipes engaged in the sleeves and communicating with the water-receptacle.

3. An oil-burner comprising a pan, a fuelsupply pipe communicating with the pan, a core disposed over the pan, said core having a water-receptacle therewithin and having a passage communicating with the water-receptacle and with the interior of the pan, and a chimney inclosing the core and having an opening in its upper end, said chimney being arranged to receive gas from the pan for discharge of said gas through its opening, said pan and core being disposed to receive heat from gas ignited at the opening of the chimney.

4. An oil-burner comprising a hollow base portion open at its top and having a plurality of openings in its bottom, vertical air-tubes engaged at their lower ends in certain of the openings and lying within the base portion, a fuel-supply pipe communicating with the interior of the base portion at the center thereof and extending above the bottom of the base portion, a pair of vertical sleeves engaged at their lower ends in certain of the openings of the bottom and lying at opposite sides of the fuel-supply pipes and extending thereabove and above theair-tubes, a cylindrical casing disposed upon the sleeves and having openings in its bottom communicating with the interior of the sleeves, said casing being open at its top, a second cylindrical casing disposed within the first-named casing with. its wall in spaced relation thereto, the second casing being also open at its top,

an open-top water-receptacle disposed within the second-named casing and lying in spaced relation to the wall thereof, said second-named casing having openings registering with those of the first-named casing, water-pipes disposed in. the sleeves and registering openings and communicating with the interior of the water-receptacle, an inverted casing disposed with its wall between the water-receptacle and the second-named casing and in spaced relation thereto, a second inverted casing disposed over the secondnamed casing with its wall between said second-named casing and the first-named casin in spaced relation thereto, a third inverte casing engaged over the first casing in spaced relation thereto, means for holding the inverted casings with their lower edges in spaced relation to the bottoms of the first and second named. casings, and a chimney disposed upon the base portion and surrounding the casings and extending thereabove.

In testimony whereof I affix my signature in presence of two witnesses.
